Unless Embraer notifies Buyer otherwise, the Aircraft shall be delivered in accordance with the provisions and schedules specified in Article 5 herein. Embraer shall give Buyer fifteen (15) days advance notice of the date on which Embraer considers that each Aircraft will be ready for delivery in the condition specified herein. Upon successful completion of ground and flight tests performed by Embraer, Buyer will receive a confirmation from Embraer of the day that the Aircraft concerned is ready for inspection and will provide Buyer within three (3) Business Days notice of the date of such inspection. b.

However, in the event of a declared strike at Embraer of relevant Embraer personnel, or a declared strike of relevant Buyer personnel, Buyer shall not be required to accept the Aircraft as provided for herein until three (3) Business Days after Embraer or Buyer provides notice that such strike has terminated. d. If Buyer declines to accept an Aircraft after its Inspection because the Aircraft failed to meet the terms of this Agreement, Buyer shall immediately give Embraer notice of all specific reasons for such refusal and [*], commencing on the first Business Day after receipt of such notice, to take all necessary actions at no cost to Buyer in order to resubmit the Aircraft to Buyer for re-inspection. e. Buyer shall inspect the Aircraft, as provided for in Article 7.b., within [*] after receipt of notice from Embraer that all necessary actions were taken ("Reinspection"). All costs of such Reinspection shall be borne by Embraer. This period as well as the one mentioned in item "d" above shall not be considered as part of the thirty (30) day grace period provided for in Article 9.b.1. f. Embraer shall ensure that the Spares for each Aircraft are available for inspection by Buyer on or before the date of delivery in accordance with Article 5.b. and shall notify Buyer of such availability. Buyer shall be allowed to inspect the Spares to be delivered in connection with each Aircraft. If Buyer finds such Spares acceptable, Buyer shall be entitled, but not obligated, to inspect the packing process, and if such an inspection is conducted, Buyer shall thereupon give Embraer notice of acceptance and receipt of Spares in question, after which notice Embraer shall not be responsible for shortages or have any liability in regard to any claim or demand whatsoever, from Buyer, with respect to such provision and Buyer shall be deemed to have waived any of its rights with respect to such delivery except for warranty claims submitted pursuant to Attachment C. If Buyer reasonably rejects one or more of the Spares during such inspection as not conforming to this Agreement, Embraer shall replace at Embraer's cost such rejected Spare or Spares with Spares which are in conformity to the Agreement. Buyer's failure, including but not limited to Buyer's refusal to perform the inspection or acceptance of all their - ----------------- * Confidential <Page> Spares after being notified of their availability by Embraer, shall not prevent Embraer from delivering such Spares direct to Buyer in accordance with Article 5.b. In the event that Buyer does not inspect the packing process as provided for herein, it shall have fifteen (15) Business Days to inspect the Spares after Buyer's receipt of such Spares and serve Embraer with written notice of acceptance or rejection of such Spares. If Buyer fails to issue the notice within such fifteen (15) days or provide Embraer with a shortage claim, it shall be deemed to waive any shortage claims. g. Should Buyer fail to comply with the procedures specified in any of the preceding items 7 (a) through 7 (e), Embraer shall not be held liable for any delays in delivery resulting from such failure. h. Should Buyer not perform its obligations in accordance with items 7(a) through 7(e) hereof within ninety (90) calendar days to be computed from the notification specified in item "a" above, Embraer shall be entitled to either terminate this Agreement with respect to such Aircraft, pursuant to Article 23.c. or, at its sole discretion, re-negotiate the terms of this Agreement with respect to such Aircraft with Buyer. If Buyer wrongfully fails to perform its obligations in accordance with items 7(a) through 7(e) hereof, at any subsequent time, Embraer shall be entitled to terminate this Agreement with respect to all unaccepted or undelivered Aircraft or related Spares pursuant to Article 23.c. below. i. Buyer shall be permitted to delegate its duties in this Article 7 and in Article 5 as to the physical Inspection, Reinspection, and acceptance and delivery of the Aircraft and Spares to its authorized representative in the form attached hereto as Schedule F. j.

In the event that an Aircraft Contractual Delivery Date must be extended by Embraer from that which is designated in Article 5, due to Buyer's failure to perform any action or provide any information contemplated by this Agreement other than the ones specified in the preceding items, and the Aircraft otherwise was to be delivered on the Contractual Delivery Date, the storage charge shall commence on the fifteenth (15th) day after the Contractual Delivery Date relative to such Aircraft. - --------------- * Confidential <Page> c.

DELAYS IN DELIVERY a. EXCUSABLE DELAYS: 1. Embraer shall not be held liable or be found in default for any delays in the delivery of an Aircraft or any Spares or in the performance of any act to be performed by Embraer under this Agreement, resulting from the following events or occurrences, hereinafter referred to as "Excusable Delays": (a) force majeure (including, but not limited to, war or state of war, civil war, insurrection, fire, accident, explosion, flood, act of government or governmental priorities (other than acts of the Government of Brazil acting in its capacity as a shareholder of Embraer), requisition, strike, labor troubles), (b) any delay to the extent resulting from any failure by Buyer to perform any action or provide any information contemplated by this Agreement. 2. Within [*] after the occurrence of any of the above mentioned events which constitute causes of Excusable Delays in delivery of an Aircraft or any Spares or in the performance of any act to be performed by Embraer under this Agreement, Embraer shall send a notice to Buyer, with a requested acknowledgment of receipt, including a description of details involved and an estimate of the effects expected upon the timing of the performance of its contractual obligations. 3. Any such delays shall extend the time for delivery of an Aircraft or Spares by the same number of days required for the cause of delay to be remedied. Embraer undertakes to use all commercially reasonable efforts whenever possible to avoid or remove any such cause of delay and to minimize its effect on the Contractual Delivery Date of an Aircraft or Spares. 4. If the cause of such Excusable Delay is such as to last longer than three hundred (300) days or to render the performance of this Agreement impossible, then Buyer shall have the option to terminate this Agreement without liability to either party, in accordance with Article 23.b. b. NON-EXCUSABLE DELAYS: <Page> 1. If the delivery of an Aircraft or Spares is delayed, not as a result of an Excusable Delay, by more than [*] after the Contractual Delivery Date for such Aircraft or, in the case of Spares, the date for delivery as agreed between the Parties in accordance with Article 5.b., Buyer will be entitled to elect to receive in accordance with item "b.3" below from Embraer liquidated damages as compensation for such delay equal to [*], up to the date that the Aircraft is ready for delivery and available to Buyer by means of confirmation of the successful completion of ground and flight tests performed by Embraer, to be provided per Article 7.a, it being understood that such liquidated damages will not, in any event, [*] and that it will only be due and payable by Embraer to Buyer after Buyer pays to Embraer the total Aircraft Purchase Price and/or Spares items price as applicable. Such liquidated damages shall be paid at Buyer's option in cash or in the form of a credit for spare parts or other Embraer- provided services. 2. The grace period of [*], or part thereof, granted by Buyer to Embraer as mentioned herein shall prevail if Embraer provides notice to Buyer advising the expected delay, provided that such notice shall be issued to Buyer [*] prior to the relevant Aircraft Contractual Delivery Date, or in the case of Spares, [*] prior to the date of delivery as agreed between the Parties in accordance with Article 5.b. The grace period shall be reduced by the same number of days Embraer delays the issuance of said notice beyond such [*]. 3. If, with respect to a delayed Aircraft or Spares, Embraer does not receive notice for liquidated damages as mentioned in item "b.1" above, from Buyer within one hundred and twenty (120) days after the Delivery Date of such Aircraft, or in the case of Spares, the date of delivery as agreed between the Parties in accordance with Article 5.b., Buyer shall be deemed to have fully waived its right to such liquidated damages. 4. If as a result of a Non-Excusable Delay, the delivery of any Aircraft will be delayed to a date beyond the Contractual Delivery Date or any revised date previously agreed to in writing by the parties, the price escalation formula set forth in Attachment D will not apply with respect to the days constituting the delay. 5. Embraer hereby acknowledges that the schedule by which the Aircraft and Spares are to be delivered as set forth in Article 5 hereof, was a material inducement to Buyer to enter into this Agreement. Consequently, it hereby represents and warrants to Buyer that in the event of a nonexcusable delay by Embraer, Buyer's delivery positions will not be unfairly prejudiced relative to the delivery positions of any other purchaser or acquirer ("Purchaser") of any - ---------- * Confidential <Page> EMB-145 aircraft, by Embraer having declared a Nonexcusable Delay in accordance with this Agreement. If Buyer's delivery positions are unfairly prejudiced for less than 15 days relative to any other Purchaser's delivery positions, such delay shall not be considered a breach of this Article 9.b.5. In the event of Seller's breach of the representation and warranty provided for herein, Buyer may terminate this Agreement in accordance with Article 23.b.1. and/or may seek damages for Embraer's breach in accordance with Article 23.a. c. DELAY DUE TO LOSS OR STRUCTURAL DAMAGE TO THE AIRCRAFT: Should any Aircraft be destroyed or damaged before acceptance by the Buyer to the extent that it becomes commercially useless, Buyer may, at its sole discretion take a replacement Aircraft under the same terms and conditions of this Agreement at a later delivery date to be agreed by the Parties. Within three (3) months after such loss, Embraer will provide Buyer with a new delivery date for a replacement Aircraft. If Buyer in its sole discretion rejects the new delivery date after further consultation with Embraer on scheduling the delivery of the Aircraft, it may terminate this Agreement with respect to such Aircraft and the Spares to be delivered with such Aircraft, by notice to Embraer given in accordance with Article 25, without any liability to either party and Embraer will return all deposits and progress payments paid with respect to such terminated Aircraft to Buyer within five (5) Business Days after Embraer receives the notice referred to above with interest at the [*] commencing on the date such deposits and progress payments were paid to Embraer. In the event Embraer fails to return the deposits and progress payments with accumulated interest to Buyer as provided for herein, Embraer should also pay to Buyer additional interest of [*] on such outstanding amounts not paid by Embraer from the date on which such payments should have been made until receipt by the Buyer. 10. INSPECTION AND QUALITY CONTROL a. Buyer is hereby permitted to have one or more authorized representatives at Embraer's facilities for a period commencing three (3) months prior to the Contractual Delivery Date of each Aircraft in order to assure that the Aircraft, Spares and Services were developed in accordance with the procedures specified in this Agreement and according to all applicable quality control standards. Buyer may communicate its concerns as to the production of the Aircraft and Spares to Embraer. b. Buyer shall communicate to Embraer the names of its authorized representatives, by means of notice, at least fifteen (15) days prior to the arrival of the authorized representatives, provided written notice is given to Embraer fifteen (15) calendar days prior to effectivity. - --------------- * Confidential <Page> c. Such representatives may also be authorized to sign the acceptance and transfer of title and risk documents and accept delivery of the Aircraft and Spares pursuant to Article 7. d. With respect to this Article 10, Embraer shall provide for use in accordance with the Agreement at no cost to Buyer, communication facilities (telephone and facsimile) for Buyer's authorized representatives, as well as the necessary tools, measuring devices, test equipment and technical assistance as may be necessary to perform acceptance tests. e. Buyer's authorized representatives shall observe Embraer's administrative rules and instructions while at Embraer's facilities, and Buyer's representatives will be provided with all appropriate rules and regulations upon arrival. f. Buyer's authorized representatives shall be allowed exclusively in those areas related to the subject matter hereof and Buyer agrees to hold harmless Embraer from and against all and any kind of liabilities in respect to such representatives, for whom Buyer is solely and fully responsible under all circumstances and in any instance except to the extent caused by the gross negligence or willful misconduct of Embraer, its officers, directors, employees or agents. 11. CHANGES a. At delivery each Aircraft will comply with the standards defined in Attachment "A" and shall incorporate all modifications which are classified as Airworthiness Directives (AD's) mandatory by CTA or FAA and shall also at Delivery incorporate any change agreed upon by Buyer and Embraer in accordance with this Article 11. b. All the specified tray-mounted avionic equipment installed in the Aircraft shall be of the latest modification standard made available to Embraer by the relevant vendor at such time as not to violate the delivery schedule of the Aircraft. All other parts will be of the latest modification standard available at the moment of scheduled installation in the Aircraft. c. Embraer may make changes in the design of the Aircraft, the definition of which and its respective classification shall be in compliance to the Aircraft type specification, as follows: 1. MINOR CHANGES: defined as those modifications which shall not adversely affect the Aircraft in any of the following: o Performance, weight or balance; o Structural strength, flight qualities, operation and/or characteristics; o Interchangeability of parts reasonably defined by Embraer as interchangeable; <Page> o Aircraft delivery, delivery dates, and prices; o Operational safety; o Ease of maintenance; o Noise and environmental control 2. MAJOR CHANGES: defined as those modifications which affect at least one of the topics mentioned in item "c.1." above. d. Embraer shall have the right, without the prior consent of Buyer, to make Minor Changes, as referred to in item "c.1" above, in the design of the Aircraft. The costs of any such changes shall be borne by Embraer. e. Major Changes as referred to in item "c.2." above which are classified as AD's mandatory by CTA and or FAA shall be conveyed to Buyer by means of Service Bulletins, approved by said authorities. Incorporation of such Service Bulletins in all Aircraft and Spares yet to be delivered to Buyer will be made by Embraer at Embraer's own costs, in a commercially reasonable period of time. Incorporation of Service Bulletins in Aircraft and Spares delivered to Buyer shall be made by Buyer at its own cost but for Service Bulletins which are issued arising from mandatory AD's issued by the FAA or CTA and which relate to defective parts which are identified by an Embraer part number ("Embraer AD's"). Such Embraer AD's shall be provided to Buyer in accordance with the warranty period provided in Attachment C. When flight safety is affected, such changes will be immediately incorporated. Whenever warranty coverage is not available or applicable, item "e" of this Article 11 shall apply. No indemnification shall be due by Embraer for the down-time of the delivered Aircraft needed for the incorporation of any such changes but for delays caused by the incorporation of Embraer AD's. In the event of delay caused by incorporation of Embraer AD's, Embraer shall be responsible for liquidated damages in accordance with Article 9.b (and the price escalation formula as set forth in Attachment D shall not apply with respect to any delay occasioned by the need to incorporate an AD). Embraer shall not be held liable for any delays in the Aircraft Contractual Delivery Date resulting from the execution of any change classified as mandatory by CTA or FAA when the Aircraft shall have already passed the specific production stage affected by the incorporation of said change. In the event that an AD is issued by the CTA or FAA prior to delivery with a terminating action date after delivery of the relevant Aircraft and Embraer has a solution for implementation of such AD prior to delivery and such implementation will not alter the delivery date of such Aircraft, Embraer will use commercially reasonable efforts to incorporate such AD prior to delivery of the relevant Aircraft . f. Major Changes (other than those which are AD's mandatory per item "e" above), any change developed by Embraer as product improvement, and any change requested by Buyer which are either Major or Minor , including those changes required by FAA <Page> as a consequence of alterations, amendments and/or innovations of its present airworthiness regulations which are in effect subsequent to the date of the Agreement but before an Aircraft Delivery Date and which are applicable to all aircraft in general as the all aircraft of the same category as the Aircraft, shall be considered as optional and, pursuant to Buyer's request, the corresponding cost proposals shall be submitted by Embraer to Buyer for consideration and approval. Should Buyer not approve any such change, it shall not be incorporated in the Aircraft. g. Any change made by Embraer in accordance with the preceding items which affects the provisions of Attachment "A", shall be incorporated in said Attachment by means of an amendment. The amendment shall be submitted to Buyer for signature thirty (30) days prior to the relevant Aircraft Contractual Delivery Date, a copy of which shall be received by Embraer, duly signed, prior to such Aircraft Actual Delivery Date. h. Except as it relates to AD's made mandatory by CTA or FAA which do not materially affect the performance of the Aircraft and Minor Changes, should an Aircraft not comply with the terms and conditions of Attachment "A", Buyer shall be entitled to either terminate this Agreement with respect to that relevant Aircraft, pursuant to Article 23.d, or, at its sole discretion, renegotiate the terms and conditions of this Agreement with Embraer. 12.

Embraer, subject to the conditions and limitations hereby expressed, warrants each Aircraft as follows: a. For a period of thirty-six (36) months from the date of delivery of each Aircraft to the first Buyer, each Aircraft will be free from: - Defects in materials, workmanship and manufacturing processes in relation to parts manufactured by Embraer or by its subcontractors holding an Embraer part number; - Defects inherent to the design of the Aircraft and its parts designed or manufactured by Embraer or by its subcontractors holding an Embraer part number. b. For a period of twenty-four (24) months from the date of delivery of each Aircraft to the first Buyer, each Aircraft will be free from: - Defects in operation of vendor (Embraer's supplier) manufactured parts, not including the Engines, Auxiliary Power Unit (APU) and their accessories, as well as failures of mentioned parts due to incorrect installation or installation not complying with the instructions issued or approved by their respective manufacturers. - Defects due to non-conformity to the Technical Description Number TD 145 /010 dated January 1998 as may be amended by Buyer's Aircraft Technical Specification referred to in Article 1.b of the Purchase Agreement of the Aircraft. Once the above mentioned periods have expired, Embraer will transfer to Buyer the original warranties issued by the vendors, if they still exist. 2. Embraer, subject to the conditions and limitations hereby expressed, warrants that: a. All spare parts which have been manufactured by Embraer or by its subcontractors holding an Embraer part number, and by vendors which will permit their particular identification and which have been sold by Embraer or its representatives will, for a period of twenty four (24) months from the date of delivery of such spares to Buyer, be free from defects of material, <Page> workmanship, manufacturing processes and defects inherent to the design of the above mentioned parts. b. All ground support equipment, which has been designed and manufactured by Embraer or by its subcontractors holding an Embraer part number and by vendors, not including Engines, APU and their accessories, and stamped with a serial number which will permit their particular identification and which have been sold by Embraer or its representatives will, for a period of twelve (12) months from the date of delivery to Buyer of said equipment, be free from malfunction, defect of material and manufacture. c. Each Aircraft is composed entirely of vendor parts and parts manufactured by Embraer and Embraer subcontractors, and the parts manufactured by Embraer and Embraer subcontractors shall have Embraer part numbers. 3. The obligations of Embraer as expressed in this warranty and as specified in Article 11.e are limited to replacement, repair or rework of the defective item, depending solely upon Embraer's own judgment, of the parts that are returned to Embraer or its representatives within a period of sixty (60) days after the occurrence of the defect, at Buyer's own expense (including but not limited to, freight, insurance, taxes and, customs duties), adequately packed, provided that such components are actually defective and that the defect has occurred within the periods stipulated in this certificate. Should the defective part not be shipped to Embraer within such sixty (60) days period, Embraer may in its sole discretion, deny the warranty claim. In the event that it is not practical in the international commercial transportation industry to return the part or component which is the subject of a warranty claim under this Attachment C, to Embraer, because of either its extremely large size or its relationship to the Airframe, then thirty (30) days after a defect is found in such structural component (hereafter referred to as "Structural Component"), Buyer shall send notice of such defect to Embraer and notwithstanding the above, Buyer shall not be obligated to return such Structural Component to Embraer. Embraer shall thereafter send an appropriate inspection team to Buyer's facilities to inspect the Structural Component for the alleged defect. In the event that Embraer in its sole judgment finds the Structural Component defective, it shall either repair, rework, or replace the defective Structural Component. Notification of any defect claimed under three (3) above must be given to Embraer within thirty (30) calendar days after such defect is found. Parts supplied to Buyer as replacement for defective parts are warranted for the balance of the warranty period still available from the original warranty of the exchanged parts. However, freight, insurance, taxes and other costs eventually incurred during the shipment to Embraer or its representative, re-installation and adjustments are Buyer's responsibility. <Page> 4. Embraer will accept no warranty claims under any of the circumstances listed below unless it can be demonstrated in accordance with the standards of the international aircraft manufacturing industry that such operation or maintenance or other circumstance did not cause the defect: a. When the Aircraft has been used in an attempt to break records, or subjected to experimental flights, or in any other way not in conformity with the flight manual or the airworthiness certificate, or subjected to any manner of use in contravention of the applicable aerial navigation or other regulations and rules, issued or recommended by government authorities of whatever country in which the aircraft is operated, when accepted and recommended by I.C.A.O.; b. When the Aircraft or any of its parts have been altered or modified by Buyer, without prior approval from Embraer or from the manufacturer of the parts through a service bulletin; c. Whenever the Aircraft or any of its parts have been involved in an accident, or when parts either defective or not complying to manufacturer's design or specification have been used; d. Whenever parts have had their identification marks, designation, seal or serial number altered or removed; e. In the event of negligence, misuse or maintenance services done on the Aircraft, or any of its parts not in accordance with the respective maintenance manual; f. In cases of deterioration, wear, breakage, damage or any other defect resulting from the use of inadequate packing methods when returning items to Embraer or its representatives. 5. The warranty hereby expressed does not apply to defects presented by expendable items, whose service life or maintenance cycle is lower than the warranty period, and to materials or parts subjected to deterioration. 6. The warranty hereby expressed is established between Embraer and the first Buyer, and it cannot be transferred or assigned to others, unless by written consent of Embraer, or as otherwise provided for pursuant to Article 16 of the Purchase Agreement of which this is an Attachment or Article 9 hereof. 7. THE WARRANTIES, OBLIGATIONS AND LIABILITIES OF Embraer AND REMEDIES OF Buyer SET FORTH IN THIS WARRANTY CERTIFICATE ARE EXCLUSIVE AND IN SUBSTITUTION FOR, AND Buyer HEREBY WAIVES, RELEASES AND RENOUNCES, ALL OTHER WARRANTIES, OBLIGATIONS AND LIABILITIES OF Embraer AND ANY ASSIGNEE OF Embraer AND ALL <Page> OTHER RIGHTS, CLAIMS AND REMEDIES OF Buyer AGAINST Embraer OR ANY ASSIGNEE OF Embraer, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY NON-CONFORMANCE OR DEFECT OR FAILURE OR ANY OTHER REASON IN ANY Aircraft OR OTHER THING DELIVERED UNDER THE PURCHASE AGREEMENT OF WHICH THIS IS AN ATTACHMENT, INCLUDING DATA, DOCUMENT, INFORMATION OR SERVICE, INCLUDING BUT NOT LIMITED TO: a.
